Residents of Japan may be shocked to learn they are technically violating the country's Radio Law by connecting computers, smartphones and tablets that have been purchased outside of Japan to domestic WiFi sites.
Although legislation says such violations are punishable by up to a year in prison or a fine of up to ¥1 million, the regulation has never been strictly enforced.
But the law is quite clear: All wireless devices sold in Japan must have a technical conformity certificate (gijyutsu kijyun tekigō shōmei, which is usually shortened to giteki in Japanese). Electronic devices that have such a certificate adhere to regulations under the Radio Law.
